POSCO Manganese Steel Utilized for Marine LNG Gas Containers

POSCO, a multinational steel-making firm headquartered in Pohang, South Korea states it's low-temperature resistant high manganese steel will be made use of in constructing the world's biggest dissolved gas (LNG)-powered mass carrier. The brand-new steel, asserted as a world first by POSCO, will be made use of for the fuel storage tank of the 50,000-ton dual-fuel LNG-powered mass carrier to be developed by Hyundai Mipo Dockyard.

POSCO will certainly begin supplying the high manganese steel to Hyundai Mipo Dockyard, Korean functional shipbuilding firm, from the third quarter of this year.

The biggest volume of any one of the LNG-powered mass providers has actually been able to lug so far is 7,000 QimingCasting bunches, yet the brand-new ship will certainly have the ability to carry 50,000 tons of products, concerning 7 times greater than the existing ones. It will certainly have an energy-efficient, green dual-fuel-capable engine that can utilize both shelter C oil and LNG. The ship will be finished at the end of following year and be made use of to bring sedimentary rock from Gangwon-do to Gwangyang works for POSCO from 2018.

As POSCO's high manganese steel consists of about 20% manganese, it can keep LNG at the exceptionally low temperature of -162 ℃. The high manganese steel that will be made use of for the LNG storage tank of the ship is superior to the existing tanks made of alloy products such as nickel as well as aluminium in terms of yield stamina, very low-temperature toughness and rate.

Since the ship will certainly be made for cruising throughout the ocean according to the International Code of Safety and security for Ships using Gases or various other Low-flashpoint Fuels (IGF Code), the high manganese steel is expected to have a better possibility at being selected as a product for exceptionally low temperature levels by the International Maritime Company once the ship goes into solution.

Based on a close participating connection with residential shipbuilders including Daewoo Shipbuilding & Marine Design, POSCO will exert to collectively build up the overseas market for high manganese steel.
